The Nintendo Wii is definitely cheaper, but the games are good. Heck, you'd probably be thrilled just playing the Wii Sports game that comes included with the Wii. It's actually a good game for exercise, and also to help you get the hang of how to use the remote and nunchuk. I'm currently playing Super Paper Mario and loving that, but it's a platformer and rpg rolled together, so I don't know how much you'd enjoy it.

Still, the Wii was made for gamers and non-gamers alike, and I can say that I love mine!
